Probably answered your own question. If the gray tank is full, water will get out the lowest point, the shower drain. Don't know if your shower has a pan or whatever for a floor, but that should have been full also, possibly overflowing, and creating the problem.You may have a shower pan leak that needs attention. good Luck.
